verify stats

[github-dub]

For the following linux fio command, should I see any verification stats on stdout or json file? I see the reads, but nothing at all about verify.

fio --ioengine=libaio --direct=1 --group_reporting=1
--name=fio_file2G
--directory=/voltest
--size=2G
--bs=8k
--iodepth=1
--rw=randwrite
--rwmixread=100
--rate_iops=100,100
--verify=md5
--verify_only
--filename=fio_file2G
--aux-path=/home/dub157/
--output-format=json

Fio will print out error messages when it encounters a verify failure. If everything completes successfully then no failures were encountered. You can test this by modifying your file and running the job again.

Verify operations are reads. Your job is a randwrite job with verify_only, so fio actually did read and verify your file. You can also run with --debug=verify,io to gain more insight into what fio is actually doing.
